We present the results of research of scantily explored close binary system V841 Cyg with possible period variations. It was attributed as /3 Lyr and as near contact binary star. We obtained light curve of the star in July 2013 in V-band. Both eclipses are partial, the depths of primary and secondary min­ima are 0m.53 and 0m.20. Light curve has feature near primary minimum: practically horizontal parts in phases ±(0.1 — 0.16). We found new time minima: HJDI = 2456504.48122, BJDH = 2456493.44562.
